Some excellent pages are paying tribute to meaningful bands/labels/concerts/flyer art etc of the time period. Really for the fans by the fans vibe's. I've contributed to all 3. Black Metal Museum Germany has a letter I received from EURONYMOUS featured on it's wall.

i'd rather like every one of these pages and have these show up in my feed all day rather than e-cards, pictures of cats, chain "like" images of children, and most of my friends status updates/links._________________good users
